ObjectiveTo provide evidence of the effectiveness of a community health intervention, that includes a cognitive stimulation program, to prevent the deterioration of cognitive abilities in our population of elderly people with normal cognition that are living in the community.DesignRandomized clinical trial (CONSORT group norms) LOCATION: San José Norte-Centro Health Center and La Caridad Foundation (Zaragoza, Spain).Participants201 people aged 65 or older, with a MEC score of at least 28 points, which were randomized between the Intervention group (101) and the Control group (100).InterventionThe intervention was applied in 10 sessions of 45minutes, one per week. It used materials designed by one of the authors, which addressed the following areas: memory, orientation, language, praxis, gnosis, calculation, perception, logical reasoning, attention-concentration and programming.Main MeasurementsThe main outcome variables were MEC, Set-Test, Barthel and Lawton-Brody.ResultsIncreases of the main result variables over their baseline level were analized. For MEC variable, the Intervention group obtained, on average, 1.58 points more than the Control group in the evaluation performed immediately after the intervention. After 6months, the improvement was 1.51 points and after a year, it was of 2.04 points. All these differences were statistically significant. For Set-Test, Barthel and Lawton-Brody variables, no statistically significant differences were observed between Intervention group and Control group.ConclusionsCognitive stimulation with our program is effective to maintain or improve cognitive performance, measured with the variable MEC, our population of elderly people with normal cognition that are living in the community. There is no evidence that this improvement is transferred to the activities of daily life measured with Barthel and Lawton-Brody variables.Copyright © 2018 The Authors.
